Biotechnology

• Messana
• Science 8

2
BIOTECHNOLOGY

• Technology based on a biological system or living
  organism
• Uses organisms to solve real world human problems
• Medicine
• Agriculture
• Food processing

3
BIOENGINEER

• Create products that meet some human need
• Research development
• Quality control
• Manufacturing production
• Agriculture

4
Biotech in Medicine

• Genetic testing picture of the DNA
• Catch criminals
• Determine parents of a baby
• Screen for diseases/genetic abnormalities
• Gene therapy utilizes viruses or bacteria to
  enter cell and replace defective genes
• Cloning creation of genetically identical
  organisms
• Dolly the Sheep
• Cloning human would be very difficult, is it
  ethical??
• Tissue culturing grow human tissues and organs
  in lab
• Development of better/cheaper drugs

5
Biotech in Microbiology

• Making bacteria that will eat harmful pollutants
• Help bacteria reproduce faster
• Bacteria will clean up after an industrial
  accident
• Bacteria will increase rate of nutrient cycling
  through ecosystem
• Microbes used to produce food products
• Control production of harmful bacteria in foods
• Control microbes in water

6
Biotech in Agriculture

• Increase crop yields
• Transgenic crops DNA altered by humans
• Insecticide use, plants that are insect resistant
• Transgenic animals produce more, faster
  products contain fewer hormones, antibiotics,
  cholesterol
• Reducing environmental stressors
• Make transgenic crops that can survive in harsh
  conditions
• Improving food quality
• Alter size, taste, amount of nutrients, when it
  ripens, how long it stays fresh

7
Ethical Issues

• Will cross-pollination between transgenic crops
  wild plants have unforeseen consequences?
• How will transgenic crops affect humans long
  term?
• Will transgenic crops affect food allergies or
  cause new unknown diseases?
• Who gets to make decisions on Human Genome
  Project info?
• Is it OK to pick desired genetic characteristics
  for a baby?
• What are the effects of genetic manipulation on
  complex human traits?
